I have a platform with objects that sit on top of it. All physic work correctly until I start to move the platform. Basically the platform moves back and forth (on x axis) with the objects on top of it. However, the objects do not "stick" to the platform's surface (like if you moved a table with plates on it, they would stay on the table (unless the table moved really fast)), they just slide off of the platform. I have set the platform to be "anisotropic" with friction values, but this does nothing. The platform itself is a regular "static actor" and the objects that sit on it are rigid bodies.
